HINGE.

Application filed December 18, 1924. Serial No. 756,772.

To all whom it may concern:

Be it known that we, HENRY MOECKEB, J r., THEODORE THOMPSON, and O'r'ro HAMMER- MEISTER, all citizens of the United States, residing at Homewood and Harvey, respectively, in the county of Cook and State of Illinois, have invented new and useful Improvements in Hinges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in hinges pertaining more particularly to a hinge and hinge housing for use upon drop doors as applied to stove ovens.

One of the objects of the invention is to provide a spring hinge and hinge casing construction wherein the tension of the spring is easily and quickly adjustable.

Another object of the invention is to provide aspring hinge the tension of which is adjustable and at the same time provide a construction which is strong yet simple and cheap of manufacture and highly efficient in operation. I

A still further object of the invention is to provide a novel form of hinge and hinge casing construction which can be fastened to the stove frame bythe use of only one bolt or screw.

A still further object of the invention is to provide a spring hinge construction wherein the spring is applied to the trunnion of the hinge in a novel manner to permit the ready and easy adjustment of the sprin tension.

Another and further object o the invention is to provide a spring hinge construction and casing therefor composed of a minimum number of arts.

Other ob ects, novel features of construction and improved results of the device will appear in the following description and accompanying drawings.

In the drawings: Figure 1 is a view in front elevation of 45 one corner of an oven door'showing the improved hinge construction applied thereto.

Figure 2 is an enlarged detail perspective view of the parts comprising the hinge and casing,the parts being shown in extended unassembled relation.

In the manufacture of stoves it is desirable in respect to the hinges of the oven doors that the hinges be of as simple a construction as possible but at the same time provide a hinge of sturdy character so that it will stand long and'hard usage. Additionally it is desirable that these hinges be spring hinges so that when the doors are in an open position and released they will automatically close themselves. Furthermore the hinges should not detract unnecessarily from the appearance of the stoves by being attached by numerous bolts, screws or the like.

Having the above enumerated facts in mind the present invention has been conceived and although the drawings show and the description describes the hinge as being attached to stove oven doors it will be readily understood that the construction could be utilized in respect to doors of other characters. 1

Referring now to the drawings, A represents the front frame. of the stove oven, B the oven door, C the oven hinge, D the .hinge .pintle or trunnion, E the hinge spring, F the hinge casing, or trunnion housing, and G the hinge or door stop.

Describing the invention more specificallyit will beseen that the hinge C comprises a vertical leg 1 and a horizontal leg 2joined to form an L shaped bracket. The j'ointure ofthe horizontal and vertical legs is bulged out as at 3 to add to the strength of and the appearance of the bracket. It will be readily understood that the hinge C can be cast in one piece. The back of the vertical and horizontal legs of the hinge are provided at their outer edges with flanges 4 and 5 while cen-' trally positioned at several points throughout the length of the two members are screwthreaded holes or openings 6.

It will be seen that the hinge member C will fit the corner of a door and support and hold the door between the flanges 4 and 5.

The hinge can be fastened securely to the door by means of suitable screws (not shown) which will enter the threaded openings 6 of the hinge.

- Cast integrally with the hinge C and extending downwardly and outwardly therefrom is an enlarged portion 7 The lower front face of the portion 7 is flat as at 8 and is provided with a slight extension 9. The purpose of the flat face 8 and extension 9 will be hereinafter described.

Extending outwardly from the enlarged portion 7 of the hinge is the circular pintle -of the openings 10, 11 and 12 the tenslon or trunnion D. Positioned in a plane about the inner end of the trunnion or pintle D in the end of the enlarged portion 7 are a.

series of openings designated by the numerals 10, 11 and 12.

The spring for the hinge is designated by the letter E and as clearly appears inthe drawings is a coil or spiral spring the end 13 of which extends outwardly in a horizontal plane from the coil while the other end 14 of the spring extends upwardly in a vertical plane from the coil.

The spring casing or trunnion housing is designated by the letter F and comprises a housing having a closed end 15 provided with an opening or aperture 16 adapted to rotatably support the outer end 17 of the hinge pintle. Additionally it will be seen that this opening 16 is centrally located in that portion 1-5 of the housing which closes the enlarged portion 18 of this member; The inner side of enlarged housing portion 18 is open as at 19. With this construction it will be seen that the coil spring E is carried within the enlarged portion 18 of the housing.

to fasten the casin'g in place.

As clearly appears in Figure 1 of the drawings the end 13 of the spring is inserted in one of the openings 10, 11 or 12 while the vertical end 14 of the spring engages the portion 20 of the casing F.

The casing F is additionally provided.

with the door or hinge stop G which comprises an extension adapted in the assem bled hinge to be in a position below or slightly separated from the enlarged portion 7 of the hinge C.

The casing F is fastened to the door by means of a screw or bolt 21 which penetrates the opening 22 in the upper end 23 of the casing. This'is the only bolt or screw used The lower end of the casing is prevented from shifting about upon the stove frame by reason of the pin 24 which is cast with and carried b the rear face of the hinge or door stop This pin 24 is adapted to enter and engage a drilled hole in the front of the stove frame. v

An assembled View of the parts compos ing the invention appears in Figure 1 of the drawings. It will be seen that the hingev is fastened to the door in a manner whereby no screw or bolt heads are in evidence.

Furthermore the hinge casing is fastened casing in this manner a certain'amount of flexibility is given to the mounting of the casing.

It will be seen that through the medium of the spring can be easily and quickly changed. Furthermore the openings 10, 11 and 12 are in the strong part of the hinge and therefore do not weaken the construction. Irrespective of what tension the spring is adjusted to the vertical end 14 of the spring will engage the part 20 of the casing.

Furthern'iore it will be seen that when the door is swung to an open position the projection 9 of the lower face 8 of the hinge portion 7 will engage the door stop G of the casing and prevent the operator from opening the door beyond this point.

Attention is further. directed to the fact that the hinge casing or housing F bears directly against the front of the oven frame thereby making the device unusually strong and solid and overcomes any chance of the device being broken or damaged by the operator opening the door violently against the door stop G.

Attention is directed to the fact that the rear face of the upper end 23 of the casing F is provided with flanged edges and that a flange surrounds the inner edge of the bglt opening 22. By this construction the cas-'.

ing will rest flush against the frame A of,he stove even though the vertical exten ing end 14 of the coil spring E is positionec between the casing and the stove frame. in other words due to this'construction the portion 20 of the casing is in reality a depression which is at least as great in depth as the thickness of the end .14 of the coil spring.
